Abstract
A method and apparatus for identifying a place where a saw may be performed. An oscillating laser beam is provided to a target according to a user preference. The user selects at least one characteristic of the oscillating laser beam in order to identify the target in an outdoor environment. The selected at least one characteristic is then provided to a motor which executes the oscillating.
Claims25
A method for sawing a log, the method comprising the steps of:
- providing an oscillating laser spot beam on a selected cut line on a log to saw in alignment with a saw blade;
- selecting a cut line on the log to saw guided by said oscillating laser spot beam;
- performing a cut with said saw blade in accordance with the provided oscillating laser spot beam on the selected cut line on the log to saw.
An apparatus for providing a visual indication of a location on an object using a laser beam provided by a laser, the apparatus comprising:
- a laser source providing a laser spot beam;
- a user selecting unit providing a selected laser beam controlling scheme signal according to a chosen vicinity of a location of interest on said object, the selected laser beam controlling scheme signal enabling a moving of the laser spot beam provided by the laser source in the chosen vicinity of the location of interest of the object;
- a positioning unit, positioning the laser spot beam using the selected laser beam controlling scheme signal;
- wherein the positioning of the laser spot beam according to the selected controlling scheme signal enables a precise visual indication of a location on the object using the laser spot beam.
An apparatus for sawing a log at a region of interest on the log, the apparatus comprising a:
- a rotating laser spot beam providing apparatus comprising a laser and providing an oscillating laser spot beam defining a plane on a region of interest of the log;
- a saw adjustable with respect to the plane defined by the oscillating laser spot beam for sawing the log;
- wherein the adjustable saw performs a sawing of the log at the region of interest using the rotating laser spot beam.
